Device and method for discharging electric charges

Abstract

The present device eliminates electrostatic discharges when getting out of the car, exploiting the principle of transfer of the surface electric charges by difference of potential. This avoids all the problems caused by electrostatic discharges: sudden explosion of airbags, problems for people with implants of any type and general discomfort caused by said discharges.
